7bcde7270d Have trans_bind_thunk handle polymorphic but statically sized return values.
Closes #775.

001df3f0ca Revert "Revert "Handle conditionals on _|_ - typed values correctly""
This reverts commit ea81c03960264bf590cd99ed2b662243e3db7a7c.

Changed the case in trans_if where the conditional is _|_ - typed
but the block is terminated to return the result of the cond,
instead of nil.

This passes "make check" with optimization disabled as well as
enabled.

ea81c03960 Revert "Handle conditionals on _|_ - typed values correctly"
This reverts commit 13f8b3f2a67a4e3a7a26b0e238e1b6ce9e1f3573.

run-pass/if-ret.rs does not translate correctly when unoptimized. Issue #797

7c34550931 Make _|_ type binopable
But don't actually generate code that does the operation. That means
hoisting the check I added in my last commit from trans_compare
up into trans_eager_binop (don't generate any code if one operand
has type _|_ ).

Closes #777

731797d075 In trans, don't assume both sides of a binop have the same type
This was at least partially responsible for Issue 777.

    The only solution I can think of is for trans to just not generate
    code for a comparison if one or both sides has type _|_. Since
    that means evaluating that subexpression diverges, it should be ok
    to never do the comparison. Actually generating code for the
    comparison would trip an LLVM assertion failure.

f8fa574864 Copy locals created by destructuring on the content of a box
This is required so that assigning to these locals doesn't clobber
the content of the box.

(A possible optimization would be to only do this copying for
locals that actually are assigned to.)

985c32ef4c Partially implement destructuring locals
You can now say

    let {bcx, val} = some_result_returner();

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.

Oops.  If we already have a backwarding vtable, that means that we are
currently building a forwarding fn.  (Progress toward issue #702.)

d1298f768c Have bind support non-alias parametric non-bound arguments.
This was previously disallowed by the typechecker and not properly handled
in trans. I removed the typechecker check (replacing it with a simpler
check that spawned functions don't have type params) and fixed trans.
Closes #756.

4de0b3d947 Allow already bound functions to be bound again.
This commit just disables the check. All of the real work was in previous
commits that moved the target function into the bindings part of the closure
that is tracked by the tydesc.
